NON-HARDENING CLAY COMPOSITE AND METHOD FOR MANUFACTURING SAME

Disclosed is a clay composition that can be used for play, education, work modeling and the like as an alternative to conventional general clay or sand, artificial clay, rubber clay, paper clay and the like. In particular, disclosed are a novel form of an environmentally friendly clay composition that is not hardened and thus maintains its original form for a long period of time and can be re-used without water, and a method for preparing the same. Provided is a novel form of clay material which is not hardened and can be repeatedly used for a long period of time, since it is prepared by mixing porous diatomite particles as a base material with an amphiprotic (hydrophilic and lipophilic) liquid, followed by kneading. The clay composition enables formation of various shapes of clays which have plasticity as an inherent properties of clay and looseness as an inherent property of soil, can be repeatedly aggregated and separated as an inherent property of sand, and have different characteristics and forms, depending on control of components and additives. In addition, the clay composition contains environmentally friendly natural substances and thus enables children to safely touch and play with the clay for a long period of time, supports various functional substances such as antibacterial substances using porous diatomite as a medium and can continuously exhibit effects of the functional substances.
